Lenm Patent No. 83,128, @ad voctober 2o, 186s.

To all whomc't :may concer-n V 'Be it known that we, WILLIAM H. Bornand 'GEORGE G. LEE, of Syracuse, in the county of 'Onon' daga, and State of New York, have 'inventeda new and useful Improvement in Growing-Machine; and we do hereby declare that .the followingis a full,.clear,

and exact descnptionthereof, 'which enable those skilled in the artto make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which A Figure 1 is a side view of a growing-machine having our improvement.

Figures 2, 3, and 4, are detail views. Similar letters of reference indicate like parts. This invention relates to certain improvements in tinners growing-machines, whereby the machine is readily converted from a machine which folds the seams down on the outside of the tin vessel or pipe Sto., to

one for. folding the seams down on the inside ofv saidA vessels,4 pipe, Snc., and thereby making a single maf chine adaptable for work which has heretofore required two machines, or a separate machinefor each method of turningdown the seams, as hereinafter more fully described.

Fig. l, -in the accompanying drawings, shows an ordinary growing-machine with our improvement attached. In place of using an arm, B, having a plain rolling-face, withv a grooved roller, A', for turning the seam on the outside, and a second machine, having a grooved arm, B, with a plain-faced roller, A, for turning seams on the inside, we channel out the face of the arm B, so as to receive and hold a bark'b, which has grooves of different sizes on three of its faces, and one plain face, as shownby cross-sections, Vligsgland f 3; or the .bar b mayl be made with asingle groove,y as l shown in gl 4;

When this bar-vb is, adjusted-1 inthe channel"' ofjv arm B, with its plain face upward, then a grooved roller, j A, is alsol adjusted to the machine, and it is Vready for outside seaming; and when inside seaming is to be done, the bar bis turned over,-to present a 'grooved rollin g-face, and a plain-faced treading-roller, A, is substituted in place of the grooved one, andby this means the machine is made adaptable for folding the seams of work on either the inside or outside, as desired, and but a single machine is required to do workl that has heretofore required two machines.

Having thus described our invention, What we'claim as new, and desire to secure by Letters Patent, is A An' arm, B, when constructed in such manner as to alternately present a plain or grooved rolling-face, as desired, substantially as and. -for the purpose herein described. v

The above specification of our invention signed by us, this 27th day of March, 1868.
